HORACE K. TALLMAGE,-OF BUFFALO, NEV YORK.

HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 405,620, dated June 18,1,889.

Application filed March 2B, 1889. Serial No. 305,051. (No model.)

To all whom, it may concern.-

Be it known that I, HORACE K. TALLMAGE, a citizen of the United States,and a resident of Buffalo, in the county of Erie and State of New York,have invented new and useful Improvements in Hot-Air Registers, of whichthe following is a specification.

This invention relates to that class of hotair registers in which apivoted damperis arranged in the lower portion of the registerbox, sothat when the register is closed the heat is shut off from theregister-box, whereby the danger of fire by the ignition of thesurrounding wood-work is avoided. A register of this kind is describedand shown in Letters Patent of the United States, No. 363,181, grantedto me May 17, 1887.

The object of my present invention is to construct the register in sucha manner that the top plate can be conveniently removed and replacedwhen it is desired to clean the register without the necessity ofdisconnecting the damper-operating mechanism from the top plate inremoving the latter.

The invention consists to that end in suspending the damper and itsoperating devices from the removable top plate of the register, as willbe hereinafter more fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical section of myimproved register. Fig. 2 is a vertical section thereof at right anglesto Fig. 1. Fig. 3 is a horizontal section in line x Qc, Fig. 1. Fig. 4is a detached view of the top plate of the register and .connectingparts. Fig. 5 is a fragmentary top plan view of the top plate, partlyinsection, showing the means whereby the sliding button is held inposition. Fig. 6 is afragmentary section of the damper and one of itssupportingarms, on an enlarged scale, showing the shoulder or stop,whereby the tilting movement of the damper is limited. Fig. 7 is afragmentary vertical section of a modified construction of the register.

Like letters of reference refer to like parts in the several figures.

A represents the rectangular box of the register having in its bottomthe usual ring or collar B, which iits into the furnace flue or pipe,and O is the top plate of the register arranged at the upper end of thebox A. In the collar B of the register-box is preferably secured acast-iron ring b.

d d represent two supporting-arms secured at their upper ends to theunder side of the top plate O, near opposite edges thereof, anddepending into the register-box A.

E represents the pivoted damper arranged in the opening in the bottom ofthe registerbox, and journaled between the lower ends of the dependingarms d d, as clearly shown in the drawings. The upper edge of the ring bis recessed to receive the lower ends of the supporting-arms d, as shownat f in Figs. 1 and 3. By seating the supporting-arms in the .recessedring the lower ends thereof are stiften ed and firmly held in place.

g represents a sliding button or knob moving in a longitudinal slot orway g in the top plate O, and h is a rod connecting the damper with saidsliding button. The connectingrod h is pivoted at its lower end to thedamper on one side of the'center thereof, and at its upper end to theshank of the button g.

t' represents iiat metallic springs secured centrally to opposite sidesof the shank of the sliding button g, and bearing with their free endsagainst the adjacent sides of the slot or way g. These springs by theirfrictional contact with the sides of the slot hold the button at anydesired point of the slot, while at the same time permitting the buttonto be moved back and forth in the slot.` By sliding the button towardeither end of its slot the damper E is opened or closed. jj', Fig. 6,represent stops or shoulders arranged at the lower ends of thesupportingarms d d at right angles to each other, or nearly so, wherebythe tilting movement of the damper is restricted in either direction bythe damper striking said stops. These stops or shoulders maybe cast onthe arms d, as shown, or they may be formed by separate plates rivetedor otherwise secured to the arms.

As the damper with its supports and tilting mechanism is suspended fromand carried by the top plate of the register, the top plate can bereadily lifted from the registerbox with these parts, when it is desiredto clean the register, without requiring any of IOC) the parts to be'disconnected from the top plate in removing the latter or to beconnected therewith upon replacing the top plate. Upon removing` thetopplate the register-box is free and unobstructed and easy of access.

If desired, a sheet-metal ring may be used in place of the cast-ironring b, or the ring may be entirely omitted. In case a sheetmetal ringis used it is preferably connected to the lowerends of thesupporting-arms d d, so as to fit into the collar B and surround thedamper, as represented in Fig. 7. This ring is employed to insure aproper iit of the damper in the register, as the sheet-metal ring of anordinary register-box is sometimes not perfectly circular, in which casethe damper would not iit closely therein in the absence ofthe ring.

I claim as my inventionl. In a hot-air register, the combination, withthe register-box and a damper arranged in the lower portion thereof, ofa removable top plate arranged at the upper end of the register-box andcarrying the damper and its supports, substantially as set forth.

2. In a hot-air register, the combination, with the register-box and adamper arranged in the lower portion of said box, of a removable topplate arranged at the upper end of the register-box and supporting-armsdepending' from the top plate and carrying the damper, substantially asset forth.

3. In a hot-air register, the combination, with the register-box and adamper arranged in the lower portion of said box, of a removable topplate arranged at the upper end of the register-box, supporting-armsdepending from the top plate and carrying the damper, and stops orshoulders arranged on said arms, whereby the tilting movement of thedamper is limited, substantially as set forth.V

. 4. In a hot-air register, the. combination, with the register-box anda damper arranged in the lower portion of said box, of a removable topplate arranged at the upper end of the register-box, supporting-armsdepending from the top plate and carrying the damper, a shifting buttonor knob arranged on the top plate, and a rod connecting the damper withsaid shifting button, substantially as set forth.

5. In a hot-air register, the combination, with the register-box, of atop plate arranged at the upper end of said box, a pivoted damperarranged in the lower portion of the registerbox, a shifting' buttonsliding in a way in the top plate and provided with friction-springs,and a rod connecting said button with the damper, substantially as setforth.

G. In a l1ot-air register, the combination, with the register-box havingan opening in its bottom, of a recessed collar fitted in 'said opening,a top plate arranged at the upper end of said box and having dependingsupporting-arms fitting in the recesses of said collar, Vand a damperpivoted between said arms, substantially as set forth.

Witness my hand this 25th day of March, 1889.
